General Safety Rules
Read all instructions. Failure to follow all instructions listed below may result in electric
shock, fi re and/or serious injury. The term “power tool” in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
fl ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
anyadapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, rang-
es and refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock. Use only 3-wire extension cords that
have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool’s plug.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. If an extension cord is to be used outdoors, it must be marked with the suffi x W-A or
W following the cord type designation. Use of a cord suitable for outdoor use reduces the
risk of electric shock. When using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. The following table shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the cord.
Minimum Gauge for Cord Sets
Volts Total Length of Cord in Feet
120V 0-25 26-50 51-100 101-150
Ampere Rating Gauge of wire in AWG units
From 6 to 10 amps 18 16 14 12
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool while you are tired or under the infl uence of drugs, al-
cohol or medication. A moment of inattention while operating power tools may result in
serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate condi-
tions will reduce personal injuries.
c) Avoid accidental starting. Be sure the switch is in the off-position before plugging in.
Carrying power tools with your fi nger on the switch or plugging in power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in mov-
ing parts. Air vents often cover moving parts and should also be avoided.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dust-
related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The cor-
rect power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tools operation. If dam-
aged, have the power tool repaired before use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these instruc-
tions and in the manner intended for the particular type of power tool, taking into ac-
count the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
5)
Service
a) Have your power tool serviced by a qualifi ed repair person using only identical re-
placement parts. This will ensure that the safety of the power tool is maintained.
ADDITIONAL SPECIFIC SAFETY RULES
• Hold tool by insulated gripping surfaces when performing an operation where the cutting
tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed
metal parts of the tool “live” and shock the operator.
• Disconnect the cord plug from the power circuit before changing abrasive discs.
• Keep the tool away from your body away from body while it is running.
• Check to see that the switch is in the “OFF” position before connecting the tool to the power
circuit.
• Anchor your ladder well and place it close enough to the work area so that you do not
have an extended reach. Work with one arm out to the side of one of the legs of the ladder
and the other arm between the rungs. Hold the tool with both hands.
• Use scaffolding when sanding large areas that cannot be reached from the ground. When
working on a scaffold, be careful regarding your footing and balance. Use a guardrail to prevent
falling.
• Do not use the spindle lock pin to stop the spindle from rotating.
• Do not sand lead-based paint. Lead-based paint should only be removed by a professional.
Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
• lead from lead-based paint.
• crystalline silica from bricks and cement and other masonry products.
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorp-
tion of harmful chemicals.
Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protec-
tion appropriate for the dust exposure. Direct particles away from face and body.
ALWAYS USE SAFETY GLASSES.(ANSI Z87.1) and (CAN/CSA Z94.3) Everyday
eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty.
ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3)
• ANSI S12.6 (S3.19) hearing protection
• NIOSH/OSHA/MSHA respiratory protection

ADDITIONAL SAFETY RULES FOR PAINT REMOVAL
1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the con-
taminated dust. The greatest danger of lead poisoning is to children and pregnant women.
2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis, we
recommend the following precautions when sanding any paint:
PERSONAL SAFETY
1. No children or pregnant women should enter the work area where the paint sanding is being
done until all clean up is completed.
2. A dust mask or respirator should be worn by all persons entering the work area. The filter should
be replaced daily or whenever the wearer has difficulty breathing. See your local hardware store
for the proper NIOSH approved dust mask.
3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting
contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or
smoking. Articles of food, drink, or smoking should not be left in the work area where dust would
settle on them.
ENVIRONMENTAL SAFETY
1. Paint should be removed in such a manner as to minimize the amount of dust generated.
2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mil thickness.
3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.
CLEANING AND DISPOSAL
1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the duration
of the sanding project. Vacuum filter bags should be changed frequently.
2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or other
removal debris. They should be placed in sealed refuse receptacles and disposed of through
regular trash pick-up procedures. During clean up, children and pregnant women should be kept
away from the immediate work area.
3. All toys, washable furniture and utensils used by children should be washed thoroughly before
being used again.

AVERTISSEMENT
À Titre Préventif, lire le guide.
1. Remove the three gear case cover screws (B) Fig. 5 counter-clockwise with a 9/64" hex
wrench.
NOTE: Retain the screws in case you want to use the power unit without the paint remover
attachment. (Using the the longer screws without the paint remover attachment will damage the
internal gears).
2. Attach the paint remover attachment on the power unit (Fig. 6). Secure it with three round head
machine screws (supplied). Tighten the screws firmly.
3. Thread the aluminum and sponge rubber back-up pad (A) Fig. 7 on the machine spindle. Hand
tighten.
4. Select the Porter-Cable tungsten carbide disc with grit size best suited for the job. Center the
disc on the back-up pad (Fig. 8) and thread the disc retaining nut on the spindle. Depress the
spindle lock pin (A) Fig. 8 and rotate pad by hand until the lock engages and stops the pad
rotation. Hold the spindle lock pin down while using the spanner wrench (B) Fig. 8 to firmly
tighten the disc retaining nut.
The Model 7403 is designed for use with specific discs and pads. The use of any other back-up
pads or discs could be hazardous.
HOW TO HOLD THE TOOL
Hold the tool firmly with both hands (Fig. 9).
TO START AND STOP THE TOOL
To start the tool, depress the trigger (A) Fig. 10. To stop the tool, release the trigger. This tool has a
lock button (B) Fig. 10, conveniently located in the tool handle. To keep tool running continuously,
depress the trigger (A) and push in the switch locking button (B) on the left side of the handle. While
holding the button in, release the trigger. To release the locking button, depress the trigger and
release.
Make certain that the switch is in the “OFF” position before connecting the tool to the
power source to avoid unintentional starting.
VARIABLE SPEED
You can adjust the speed of this tool by turning the thumbwheel (C) Fig. 10. Thumbwheel position
#1 provides the slowest operating speed (3300 RPM) and position #6 the fastest (4500 RPM). You
can change the speed while the motor is running or not running.
ADJUSTING GUIDE SCREWS
To reduce the risk of injury, turn unit off and disconnect it from power source
before installing and removing accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
For most applications, position the buttonhead guide screws (A) Fig. 11 so that a straight-edge (B)
placed on them will just barely clear the pad edge (C). In this position, the pad rim will not rub the
clapboard edge on which the screws ride. You can adjust the screws to keep the pad edge farther
away from the overlapping clapboard. To change the positions of the screws, loosen the lock nuts,
adjust the screws and tighten lock nuts. Make sure the screws do not turn or change position while
tightening lock nuts.
ADJUSTING SIDE RAILS
To reduce the risk of injury, turn unit off and disconnect it from power source
before installing and removing accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
Two knobs (A) Fig. 12 are provided for controlling the movement of the side rails, above or below
the pad. For manual instruction purposes, the right knob is on the same side of the motor frame
as the sander handle. The right side rail is controlled by this knob. To lower the right side rail, turn
the right control knob toward the front of the machine. To raise the right side rail, turn the right
control knob toward the rear of the machine. To lower the left side rail, turn the left control knob
toward the rear of the machine. To raise the left side rail, turn the left control knob toward the
front of the machine.
The distance of the rails above and below the pad edge determines the depth of cut. For most
applications, satisfactory operation will result when one side rail is adjusted so it is 1/32" above
the pad edge, and the other rail 1/32" below the pad edge (see Fig. 12). For removing very thin
coats of paint, make the depth of cut smaller by moving the rail above the pad downward. Use a
piece of scrap lumber to try several positions until you find the height best suited for the job. Do
not change the position of the rail that is 1/32" below the pad edge.
SPOT SANDING
To sand small areas, start the motor and place the button-head guide screws against the edge of
the clapboard above the sanding area. Lower the abrasive disc on the clapboard and move the
machine back and forth from left to right until the paint has been removed (Fig. 13). To sand close to
the edge of the board above, tilt the tool forward.
To sand the lower part of wide clapboards, move the tool down and up, back and forth from left to
right, and in circles. To spot sand from a ladder, firmly anchor the ladder close enough to the work
area to prevent excessive reach. Work with one arm outside one of the legs of the ladder and the
other between the rungs of the ladder (Fig. 14).
SANDING LARGE AREAS
Use a scaffold to sand large areas that cannot be reached from the ground. Sand in the same
manner that you would sand small areas - left to right, right to left, up, down, or in a circular path
until you have covered the entire surface.
SANDING UP TO WINDOW OR DOOR FRAMES
If the window or door frame is on your left, adjust the left rail of the paint remover so that it is higher
than the edge of the pad. Adjust the right rail so that it is lower than the edge of the pad. If the
window or door frame is to your right, adjust the rails in the opposite way.
REMOVING PAINT FROM PORCHES
To remove paint from porches, raise one rail above the pad edge and lower the other rail below the
pad edge. The machine can be moved from left to right, right to left, or in circular paths (Fig.15).
FLOOR EDGING
Adjust the paint remover guide screws so that paint can be removed up to the intersection of two
surfaces. This, coupled with the light weight and ease of handling, makes the Disc Sander–Paint
Remover ideal for secondary floor edging jobs.
SANDING MASONRY
The Paint Remover is excellent for preparing masonry surfaces for painting. Use a #24 or #36 grit
carbide disc for this job since the grit on paper discs is quickly destroyed. Masonry is sanded in the
same manner as wood.
